What is the difference between acute kidney injury and chronic kidney disease?

Patients experiencing acute kidney failure are placed on a special diet, fluid restrictions and temporarily dialysis until their kidneys heal. With treatment, kidney function may return to normal. Chronic kidney failure develops over a long period and is generally not reversible.

How can you tell the difference between AKI and CKD?

The management of AKI involves identifying and treating the underlying case as well as minimizing complications. AKI is usually reversible. In contrast, CKD develops gradually, over months to years, as a result of chronic illnesses such as diabetes and hypertension.

Is acute kidney injury the same as chronic kidney disease?

AKI is a sudden loss of kidney function; CKD develops slowly over many years. Common risk factors of each include advanced age, diabetes and high blood pressure.

Why is it important to differentiate between AKI and CKD?

Distinguishing AKI from chronic kidney disease is important, yet making the distinction can be difficult; chronic kidney disease is itself an important risk factor for AKI. A history of chronic symptoms—months of fatigue, weight loss, anorexia, nocturia, sleep disturbance, and pruritus—suggests chronic kidney disease.

How is acute kidney injury diagnosed?

Doctors diagnose acute kidney injury by measuring the level of creatinine in the blood. (Creatinine is a chemical waste product removed by the body entirely by the kidneys. If the kidneys are not working properly, there will be an increase in levels in the blood.) Decreased urine output can be observed by a doctor.

What are the three classifications of acute kidney injury?

The causes of acute kidney injury can be divided into three categories (Table 29): prerenal (caused by decreased renal perfusion, often because of volume depletion), intrinsic renal (caused by a process within the kidneys), and postrenal (caused by inadequate drainage of urine distal to the kidneys).

Is acute kidney injury serious?

Acute kidney injury (AKI) is a sudden decline in the ability of your kidneys to work and perform their normal functions. AKI is sometimes called acute kidney failure or acute renal failure. AKI is very serious and needs to be treated right away to prevent lasting kidney damage.

How long does it take to recover from acute kidney injury?

In some cases AKI may resolve in a couple of days with fluid and antibiotics. In other cases the illness affecting the kidneys and the rest of the body may be so severe that recovery takes two or three weeks or even longer.
